Is it possible to customize the groupings of keywords which govern syntax
highlighting in EPIC 0.5x? I can't find anything equivalent to EPIC 0.3x
modes/perl.xml file which enabled you to do this as well as add keywords
to the ones defined by EPIC.
Thanks.

The current parser is ANTLR-based and not intended to be customizable. If
you wish, you can try the procedure described at http://e-p-i-c.sourceforge.net/devguide/devguide.html
and have a look at org.epic.core.parser (files perl.g and PerlLexerBase.java;
keyword sets are defined in the latter one).
The perl.g code is unintuitive, basically a series of evolving tweaks necessary
to 1) support the syntax highlighting test cases from org.epic.perleditor-test/workspace/EPICTest/syntax.pl
and 2) keep the performance at an acceptable level.

Thanks for the info. I see from the code that you dropped the KEYWORD3 set,
which is a problem if, like me, you prefer core Perl functions and vars
to have different highlighting. Was KEYWORD£ dropped for performance reasons?

The contents of KEYWORD3 were merged into KEYWORD2. For instance, I do not
see why one would want to highlight differently 'printf' (used to be KEYWORD2)
and 'sprintf' (used to be KEYWORD3)?

I agree that it does not make much sense to highlight 'printf' and 'sprintf'
differently but I find that highlighting schemes which distinguish between
variables and core functions make the code more readable.
Still, this is only a minor quibble which does not diminish my appreciation
of the effort you put into making Perl work under Eclipse. Thanks.

So you just want to be able to make variables appear another color than
keywords? This is an easy fix (indeed, I see that Keyword3 still appears
in the Preferences; I can easily add 'Variable' there).

Yes, this is what I was suggesting. Adding it as a 'Variable' item to the
prefs dialog will make it even clearer.
